Struggles Within the Middle East: United States Supplying Israel During

In October of 1973, a war between the Arabic states of Egypt and Syria and the state of Israel broke out known as the Yom Kippur War. Being vastly overwhelmed by the Arabic states in terms of sheer volume of troops and equipment, Israel turned toward its ally in the West, the United States. With profound diplomatic pressure from multiple Arabic states, the United States found itself in an increasingly difficult position. In an effort to create the best outcome for America in both the Middle East and the global theatre, the United States made the decision, knowing full well the possible consequences, to help supply Israel during the Yom Kippur War. On October 6th, 1973, during the Jewish holy day of atonement, Yom Kippur, a surprise attack transpired, catching Israel off-guard and potentially putting over sovereign nations in a precarious position pertaining to Middle Eastern foreign affairs. The governments of Egypt and Syria, knowing that Yom Kippur was the holiest Jewish day of prayer and fasting that the Jewish military actively participated in, knew that they would be able to catch the well-defended Israeli positions off-guard. By combining their military might, the Egyptian army created a combined force that totaled the forces of NATO in Western Europe, creating a potential security threat to first world nations. In Golan Heights, the Syrian tank force outmatched Israeli by nine to one, and in the Suez region the Egyptian forces outnumber the Israeli by a ratio of one-hundred and sixty to one. Both sides, willing to commit both their men and equipment, were willing to sacrifice in order to gain their necessary victory. W illing to sacrifice their equipment, all sides in the war were looking outward toward other nations in or... ...rael during the war. With a fear that failure to maintain the balance of power in the Middle East, while trying to drive Soviet influence out, could upset America’s interests and security in the Global theatre, United States officials made the decision that supplying Israel during the Yom Kippur War was in America’s best interest the long term.

Pan Africanism and Marcus Mosiah Garvey Jr. - 1161 Words

Marcus Mosiah Garvey, Jr was a Jamaican political leader who accomplished many things within his lifetime. He was a well-known publisher, entrepreneur, journalist, Black Nationalist, as well as Pan-Africanist. Pan Africanism is the idea that all African American people possess a common cultural legacy extending from Africa. In saying this, all African Americans should work together in maintaining the culture and removing expatriate power. Marcus Garvey was important because he aided in inspiring a mass movement amongst African Americans. Garvey make efforts to show African Americans economic empowerment meanwhile sharing the importance of taking part in politics and have greater impacts. Along with these many accomplishments, his biggest accomplishment was becoming the founder of the Universal Negro Improvement Association and African Communities League in Jamaica. Garvey came to the United States in 1916 and launched the New York Division of the UNIA the following year. This association started off with merely thirteen members and exponentially grew to approximately 3500 members. Garvey has reached new heights of power within his career in the late 1920s when he headed an international convention in Liberty Hall, containing frequent delegates in attendance from 25 countries. Garvey also led a parade of over 50,000 throughout all of Harlem.
